A case of isolated chronic severe aortic regurgitation with Jaccoud's arthropathy involving the foot is presented. The interesting feature of the case is the absence of history of acute rheumatic arthritis at any stage of the illness. The diagnostic and possible therapeutic significance of this otherwise uncommon and benign condition are discussed.
The mechanics, anatomy, and pathomechanics of traumatic dorsal dislocation of the first metatarsophalangeal joint are discussed. There are two basic types of dislocations. In Type I, dislocation of the hallux with the sesamoids occurs without disrupting the sesamoid mass. Such cases are usually irreducible on closed reduction, the metatarsal head being incarcerated by the conjoined tendons with their intact sesamoids. In Type II, there is either associated disruption of the intersesamoid ligament (Type IIA) or a transverse fracture of one of the sesamoids (Type IIB). In Type II, the sesamoid disruption usually permits closed reduction.

Injury to the metatarsophalangeal joints in sports has become an increasing problem with the advent of more flexible shoewear and artificial playing surfaces. These injuries vary from mild sprains to severe tearing of the capsuloligamentous complex including avulsion fractures. This may include a compression fracture of the metatarsal head in the more severe cases. At the extreme, dislocation or fracture-dislocation of the metatarsophalangeal joint occurs. The findings in 62 cases of these injuries in Rice University athletes from 1971 to 1985 are presented. Treatment follows a standard regimen of ice, taping and anti-inflammatory medication with gradual return to sports activity as symptoms allow. Recommendations for preventive therapy include stiffening the forefoot in athletic shoes or the use of an orthotic device. This should reduce the incidence of long-term sequelae.
The extraosseus and intraosseous circulation to the first ray was evaluated by means of vascular injection techniques. The first metatarsal and metatarsophalangeal joint receive their blood supply from the first dorsal metatarsal artery, the first plantar metatarsal artery, and the superficial branch of the medial plantar artery. These three source arteries provide variable numbers of branches to the base, shaft, and head of the first metatarsal. Ramifications of branches to the head form an extensive capsular network that is more consistent and abundant on the dorsal and lateral aspects of the joint. The source of intraosseous vascularity consists of a diffuse network of fine periosteal arteries enveloping the diaphysis of the metatarsal, a single nutrient artery that perforates the first metatarsal at the lateral aspect of the shaft distally, and a system of metaphyseal and capital arteries that appear to constitute a major source of blood supply to the metatarsal head.
A method of surgical correction of a fixed hammertoe deformity is presented. It incorporates the resection of the head of the proximal phalanx with an extensor tendon tenodesis to the dorsum of the proximal phalanx. The controlled tension in the extensor tendon provides the necessary stability. It alleviates the use of K-wire fixation.

The two-stage capsular closure modification of the V-Y capsulorrhaphy in hallux abducto valgus surgery is a technique for restoring the soft tissue anatomical relationships of the first metatarsophalangeal joint in a bunion deformity. The first stage of the V-Y capsulorrhaphy corrects the plantar and lateral deviation of the abductor hallucis tendon. The second stage of the V-Y capsulorrhaphy closure allows for the correction of abductus and valgus rotation of the hallux. Inasmuch as each element of the soft tissue deformity in hallux abducto valgus deformity is corrected individually, greater precision can be applied to each constituent of the hallux abducto valgus deformity.
A case of medical fracture dislocation of the hallucal interphalangeal joint is presented. The patient did not recall the specific mechanism that caused this injury. However, this type of injury would have to entail a substantial lateral-to-medial force at the distal phalanx. The authors' review of the literature did not reveal a similar case involving a medial dislocation of the distal phalanx. This transverse plane pathology was treated with closed reduction because of a lack of sesamoid or volar plant involvement in the joint.
Painful lesions on the plantar aspect of the interphalangeal joint of the great toe respond well to surgical excision of the accessory bone found lying superior to or within the flexor hallucis longus tendon. Several incisional approaches are available, each with potential advantages and disadvantages. Failure to consider each incisional approach and address concomitant deformities may result in a less than desirable postoperative result.
In this article, the author discusses the general concept of of capsule reconstruction and emphasizes the importance of discriminative judgement in in capsule reconstruction. He reviews capsular composition and histology, as well as varied capsulotomy procedures.
